'i Hcitizen'@of`the`llnited States, residing at Cleveland, intheV county of: Cuyahoga and vState of "Ohio,v have` Vinvented certain new :and useful li'nprovements in Coal-Drilling M achines,of whic'hjthe following is aV specication,referencebeing had to they accomfijeadirly..,carriedl p ,includingran.aaeijfengaging means and an runies drawii'lse My invention' yrelates'. to drilling 4apparatus', and,particularly to machines for drilling coal` prior to putting in a blast dowiithe .breast of.. the coal.

to break .@"{Thcg.primal-)j object of my invention is 15Y the :pi-ot'i'sion of i veryy simpleand yet light and portable.machine,which may be `folded into'jelatively.small compass so. as,J to be bya miner, this machine aujafcr dri if'in'glmeans.

Beferringto-these figures it will be seen that the trame of my machine includes the oppositely disposed approximately `parallel vertically extending" sidebarsQ which are 'spaced from each other aunitorin distance. The lower ends of the side bars are connected to each other by means of a. casting 3 rigidly connected to the lower ends of the Speeication of Letters Patent.

dinally extending 'borewithin which i'sdisposed theV shank 6 'of a supporting claw, `'l' Vwhich is adapted to engage tliefloorogt'the shaft and is pronged or ,sharp pointedsofas to be forced into the floor. A4 setscrew or other means 8 is provided for holding-this stemor shank 6 in adjustedpo'siti'onl'relw' @tive to the casting 3 through which fthe vshank passes.' j y '.At'the upper end of `the bars 2f theieis provided a casting 9` which kis rigidlyjbolted to the frbarsQor otherwise' connected thereto 5 and which is formed with `a central sleeve ment with an exteriorly screw threaded shank llthe extremity of which ispointedf This shank is rotatable within the screw threaded sleeve by means of the hand `leverlQ or like means. This practically, `orinsla jack and by rotatingthe screw llit'inaybeforced upward or moved downward, and'if forced upward the pointed end will lbe forcedfinto the roof of the mine thus supporting th l() interiorly screw threadedfforffengageframe firmly in place between the walls and floor and adjacent the breast ofthe coal.

Slidingly mounted upon .the bars' iszga rectangular collar 13 which embraces. vthe bars 2 and moves slidin'gly thereon. 1fllhis collar is held in engagementwiththe-bars" by any suitable means, as by means ofsset screws lll. This collar carries upon 4ita rotatably mounted yoke .of ordinary :form

extending between the bars 2fandfprovided with ak medially disposedl seatl-or en- I gageme'nt with a screw threadedv drillI rod 16. Also slidably mounted upon thecbars` 2 is a collar 17 Whichis heldinadjustedcposition by means of a vset screwdS and which is engaged by upwardly extending bracingl rods 19.v rlhe lower ends of these bracing rods are pivoted in eyes formedy uponthe collar 17. 4 The upper ends of the rods are connected tosupporting bar-s 20. There are two of these'supporting ybars jdisposed inv spacedi'elation to each other. Theforward ends of each' of these bars-is hooked, as.. at

The collar 13 is formed. with. depending sidoineinbers,22,each provided ,withy a pin 23 and thus the bars Q0 are supported in operative position,

Slidably mounted upon the supporting bars 2O for longitudinal movement there- :plurality olf' perforations through any tof" fwhich perforations passes i al pin y23.. .g The hooks if() arendapted. to engage1-with- .the

' bearings for a transverse shaft 25 having a crank 26. The inner end of the member 23 Supports a collar 27 which is engaged with 'the rear end of the screw threaded feed shaft 16. Mounted upon the collar is a gear wheel 28' which meshes with a gear wheel 29 carried upon the shaft 25. It will therefore be obvious-that by rotating the shaft 25 rotation will be communicated to the shaft 16. The rotation of the shaft 16 and the screw threadedfcollar or Abearing 15 will cause the shaft toA feed forward and the slide 23 will be drawn along the rails or bars 20. vThe shaft 16 at its forward end carries a socket 30 adapted to receive the rear extremity of the shank of the auger or drill 31.

In use the machine will be mounted as 'illustrated in Fig. 1. The rotation of the crank 26 will cause the auger to be operated and fed forward at the same time. The collars 13 and 17 may be vertically shifted upon the side bars 2 and held in any adjusted position, thus raising or lowering the auger and adjusting its angular relation. While.the frame composed of the side bars 2 is held from rotation by the double prongs on the member 7, yet by releasing the set screw 8 the members 2 may be rotated with relation to the shank 6 and the shank 11 to thus change the angular direction of the auger. When the 'operator wishes t0 move or shift the drill he disengages the screw pin 12 from its engagement with the roof, having previously disengaged the hooks 2() from their engagement with the pin 23 and then shifted the parts to the position shown in dotted lines in Fig. 1. This permits the device t0 be readily transported.- It is possible also by shifting the collars 13 and 17 in relation to each other to change the angles of the bars 20 and thus change the angle of the drill or auger.

-While I have illustrated alform of my device which I believe to be particularly effective, I do not wish to be limited thereto as it is obvious that many changes might be made without departing from the spirit of the invention.

Having thus described my invention, what I claim is: Y

1. A drilling machine including oppositely disposed vertical supporting bars, a member slidably mounted upon the bars for vertical adjustment, spaced drill supporting bars detachably engaging with said member and extending rearward therefrom, a member disposed below the rst-named slidably adjustable member and slidably engagedfwithsaid vertical bars for vertical adjustifient, braces pivotally engaging the drill .with one of said collars, braces pivotally connected to said bars and pivotally connected to the other collar, means for hold- .ing said slidable collar in any adjusted-position, a drill shaft operatively mounted upon said bars, and means mounted upon the bars for rotating and feeding the shaft.

3. A drilling apparatus of the. character described including spaced vertical bars, members connecting the upper and lower ends of the bars, roof and licor engaging members vertically adjustable through said connecting members, a slide mounted upon the supporting members for vertical move ment, means for holding the slide in adjusted positions, a yoke mounted upon the slide having a drill shaft bearing, bars detachably connected at their inner ends to said slide', a member slidably mounted upon the bars, a drill shaft supported in said bearing and r0- tatably supported in said member, means mounted on the bars for rotating the shaft, said means being mounted upon said slidable member, braces pivotally connected to said bars and dependlngV downward therefromfa. slide adjustably mounted upon the said supporting bars and to which the lower ends of said braces are pivotally connected.

4. In a drilling apparatus of the character described, a supporting member having means at its upper and lower ends for engaging respectively the roof and Hoor of a tunnel, a vertically adjustable collar mounted upon the supporting member and supporting a screw threaded eye, a drill shaft supporting frame including spaced parallel bars having hook-shaped ends, pins projecting from said collar which the hook-shaped ends of the bars are adapted to detachably engage, braces pivotally engaged at their-
